I have a problem going on with my headphone jack. And its a pretty odd one if i do say so my self. So i had a pair of headphones that i have been using for the past year with no problems at all, but out of nowhere i start to hear a static sound over sound, and the audio is muffled. I then tested these headphones on my phone and had the same problem. I thought that my headphones were broken so i started to use a different pair, and after about a week of using them i have encountered the same exact problem. The sound is muffled, and i hear a static. Considering i have had the same EXACT problem with more than 1 pair of headphones now, ive started to think that maybe my computers headphone jack is messing them up. Because not only do they not work on my computer anymore, but they do not work on other devices as well. I have absolutely no idea what to do, do i need a new sound card? do i need a new headphone jack? (if that is even a thing). Please help me figure out what to do if you can.
